Me and Felix's robot that's is scooping up regolith and putting it in the bucket but we didn't have a enough time to do it so we just posed it for pictures. It was hard to build the robot and the box for the regolith. As me and Felix built the box regolith it took a lot of duck tape to tape the cardboard together. The website I used. The robot was fun to make although it was hard to finish it though
